HI
When we execute sh run command on 45xx or 65xx switch , cpu spike momentarily to >85 & ssh process is taking most of the cpu cycle
This is normal how IOS behave or something we need to check

Do you have very large configs? I wouldn't worry about this since traffic should be forwarding fine during that event as well. Is the CPU usage low otherwise?

HI,
Our config size is bit high
Apart from the time, when we run the command CPU is low
Is there any way to put some command to fine tune the same
Find 1 command, but not sure about the Impact, Pls suggest
parser config cache interface
